This is an attempt to simulate the pcm signal and drive a Ford alternator outside of the vehicle
Modern Ford alternators (Gen 6, & the Gen 4 from 2003) need to receive a signal from the pcm (power train control module) inorder to generate any power.
This signal is pwm with a frequency of 125mhz and a duty cycle ranging from (5% for 12v) to (95% for 16v) output. This is an Arduino sketch attempting to simulate that input signal
using an Arduino Uno r3.
*To make use of this sketch you will need to download and install the library located here: https://github.com/jpmarques19/arduino-pwm-frequency
**Update the alternator I had intended to use with his has a bad voltage regulator. (I got it off of Craigslist for $8 so I can't say I'm shocked.) Given that I am unable to continue with this project at this time. :(
Hopefully I will be able to return to it in the near future, or someone comes along and incorporates it into something useful. I had planned to add the following:
-
Add potentiometer to adjust the duty cycle and output voltage instead of having to flash a fixed duty cycle onto the Arduino.
-
Make use of the PWM signal put out by the alternaor's stator to enable automatic adjustments for steady voltage output under varying levels of load.
-
Create and upload a gerber file and a component list so that a pcb can be easily created.
